摘要： A high-capacity fluid pump comprising a dedicated lubrication system in fluid communication with the pump's drive assembly to reduce wear of internal components within the gearbox, as well as a drive shaft-supported impeller and outboard head to reduce deflection. Moreover, the blades of the outboard head are preferably shaped to decrease the inlet's cross section and stabilize incoming fluid, thereby reducing cavitation, pre-rotation, and turbulent flow at the pump inlet and increasing the overall velocity of incoming fluid.

摘要： A power recovery speed control apparatus for use in a system driven by a substantially constant-speed power source driving a turbine type water pump. The system includes a hydromechanical trimmer device controlled by pump output pressure to modify the turbine pump speed over a relatively small range as a function of pump output pressure. In series between the power source output shaft and the turbine pump drive shaft is a mechanical differential gear assembly having input, output and differential (speed difference) shafts. A fixed displacement hydrostatic transmission unit (pump) extracts a fraction of the source power at the differential shaft and applies it through hydraulic feed lines to a variable displacement hydrostatic transmission unit operated as a hydraulic motor. The hydraulic motor unit has its displacement controlled by a pump output pressure sensor and its output torque is introduced into the power train at the power source output or alternatively, at the turbine pump input shaft.

摘要： The planetary gear comprises a sun wheel seated on an impeller shaft of a jet engine, planet wheels rotatable on bearing pins which are clamped at one side, and a hollow wheel ring gear. As a result of centering by the planet wheels, the sun wheel provides a bearing for the impeller shaft and the hollow wheel provides a bearing for a slow shaft of an electrical engine. Another bearing for the slow shaft may be designed as a radial/axial bearing arranged in the gear housing. The hollow wheel 10 itself is radially elastic and is fastened to the shaft by way of a thin-walled annular extension.
